What an RSI Under 30 Tells You
RSI measures how lopsided gains and losses have been, on a scale from 0 to 100.
The Classic Oversold Line
J. Welles Wilder set 30 as the oversold line in 1978, and traders still watch it. On weekly bars it is rare: a stock needs months of losses outweighing gains to get there. That is when selling pressure tends to exhaust itself.
How It Is Computed
For each constituent we take up to ten years of weekly closes from Yahoo Finance and compute Wilder’s 14-period RSI, smoothed over the whole series. The screen matches under 30. A stock needs a full year of history to be screened.
What It Is Not
Oversold can stay oversold. A business in real trouble can carry an RSI under 30 all the way down. The filter shows how one-sided the selling has been, not that it is over or that the price is cheap.
